Suppose you have a triangle whose vertices are A, B and C, and the sides opposite these vertices are a, b and c, respectively. Cut out the triangle. Fold it so that vertex B meets vertex C. Mark the point where this fold is on side a. Mark this point as D and fold along AD. Fold it so that vertex A meets vertex C. Mark the point where this fold is on side b. Mark this point as E and fold along BE. Fold it so that vertex A meets vertex B. Mark the point where this fold is on side c. Mark this point as F and fold along CF. The three folds, AD, BE and CF meet at the circumcentre. You do not need all three - any two of them will do.
A triangle with two lines of symmetry does not exist. It can have one line of symmetry (an isosceles triangle) or three (an equilateral triangle), but not two.
There are no inequalities when it comes to addition and subtraction. Both formulas are designed to secure precise and concise equations. This goes for positive numbers, along with negative numbers.
Use the information you're given and didn't mention in the question, along with all the formulas and equations you know that talk about the relationship among parts of triangles, to calculate the unknown numbers from the known numbers.
The numbers 1-9 sum to 45. If they are to be sum to 15 on each of three sides of a triangle, no number can be counted more than once (15*3 = 45). That is, there are no numbers at any of the vertices. Then there are several possible options: 1, 5, 9 along one side, 2, 6, 7 along the second 3, 4, 8 along the third. So, if x marks the vertices . . . . .x . . . .1 . 2 . . .5 . . . 6 . . 9 . . . . . 7 . x . 3 4 8 . x
A 30-60-90 right triangle
Pythagoras's Rule does not work if the triangle is not a right angle triangle, that is having one angle equal to 90 degrees. (The rule can still be applied by creating right angles along one or more sides, using lines perpendicular to the side.)

The probability theory was his contribution, along with the Pascal's triangle.
A rhombus
Along the height it is hb^3/48 and along base it is bh^3/36
They go to the Bermuda Triangle, along with all your other lost things. Thats " Bermuda Triangle "
The medians of a triangle are concurrent and the point of concurrence, the centroid, is one-third of the distance from the opposite side to the vertex along the median
The Duval triangle is a diagnostic tool for oil insulated equipment. The three sides of an equilateral triangle form the axes representing the relative concentrations of methane (CH4), ethylene (C2H4) andacetylene (C2H2).The methane concentration is plotted along the axis with a positive gradient, ethylene along the axis with the negative gradient and acetylene along the horizontal axis : but going in the from right to left.The triangle is divided into a number of zones which indicate the most likely cause of failure.The Duval triangle is a diagnostic tool for oil insulated equipment.
